Jennifer, who has actually worked out with Kirsch in the past, shared three back-to-back videos on her Instagram story to show off her tandem sweat session with her bae. First, Alex is seen doing push-ups, alternating between placing his hands on the ground and two step platforms, followed by Jennifer (wearing supercute patterned leggings, might we add) doing some sit-ups with a medicine ball. In the last clip, Jennifer lays on top of A Rod while he flawlessly does push-ups.

Now that's what we call one hell of a partner workout! Ahead, catch a glimpse of the photos of their joint exercise routine.
